Title: Enzymic oxidation of hydrocarbons alcohols and aldehydes
IPC: C12P7/40
Filed: 1971-05-05
Abstract: 1386393 Enzymic oxidation BRITISH PETROLEUM CO Ltd 27 April 1972 [5 May 1971] 13134/71 Heading C2C An alcohol, aldehyde or acid is prepared by the enzymic oxidation of a substrate of a waterimmiscible or insoluble hydrocarbon, alcohol or aldehyde dissolved in an amide of formula where R 1 , R 2  or R 3  represent hydrogen or a C 1  to C 5  aliphatic group, dispersed in an aqueous buffer with a pH 6-5 to 9À5, to give a mixture of from a trace to 50% by volume of the substrate in the amide, and maintained at 20-38‹ C. in the presence of oxygen. Substrate with at least 6 to 20 carbon atoms, e.g. n-decane, n-hexadecane, 1-decanol, 1-tetradecanol, 1-10-decandiol, and 1-10-hexadecandiol is preferred. Single enzymes or enzyme complexes may be used and co-enzymes such as nicotinamide adenine dinucleotide or nicotinamide adenine dinucleotide phosphate may be included. Suitable amides are N,N-dimethyl formamide, formamide, N,N-diethyl formamide, N-ethyl formamide and N-methyl formamide. Examples describe the oxidation of decane to decanol and decanoic acid, and 1-10-decane diol to 10- hydroxy decanoic acid using Candida tropicalis with dimethyl formamide.

Title: Catalytic copolymerization of mono- and di-olefins
IPC: C08F36/04
Filed: 1962-04-06
Abstract: High molecular weight elastomers are formed by subjecting butadiene-1, 3 or isoprene and butene-1 or isobutylene to the action of an Alfin catalyst which is a mixture of an alkali metal, e.g. sodium, alkenyl or benzyl, alkoxide and halide, e.g. chloride. The alkenyl may be derived from an aliphatic olefine, e.g. allyl, and the alkoxide from a methyl alkyl carbinol, e.g. CH3.CH(OH). R where R is a methyl, ethyl or propyl. The monomers may be polymerized in an inert hydrocarbon solvent at 25 DEG C. minimum.  The copolymer may have a dilute solution viscosity of 6-20.  The polymer may be mixed with a process oil or with sulphur and cured, or with di-tert.-butyl hydroquinone as inhibitor. Specification 872,163 is referred to.
Patent GB-628804-A (GB)
Title: Improvements in or relating to the regulation and controlling of alternating current line voltage
IPC: H02P9/26
Filed: 1944-07-12
Abstract: 628,804. Automatic voltage control systems. SUBMARINE SIGNAL CO. July 12, 1944, No. 13322. Convention date, Sept. 17, 1940. [Class 38 (iv)] In a voltage regulating system for an alternator, having its field winding energized by a D.C. exciter, in which vacuum tube circuits vary an impedance in series with the exciter field winding, one of the vacuum tubes has a control grid on which opposing potentials are applied in series ; one relating to the exciter voltage and the other a rectified potential proportional to the A.C. current load. As shown in Fig. 1, an impedance 6, in series with a field winding 5 of a D.C. exciter 3 which supplies the field for an alternator 1, can be short circuited by means of a relay 10 which is operated by a relay 27, the coil of which is energized by a vacuum tube 15. The opposed potentials are applied to the grid 14 of a valve 11. A negative potential is applied to the grid by a rectified A.C. voltage which is proportional to the main load current or voltage. In opposition to this a positive potential is applied by the D.C. exciter through contacts 4 and rheostat 21. A bias battery 20 also supplies a negative potential to the grid. An increase in load current causes an increase of the negative potential applied through the rectifier 29. This causes the plate current of valve 11 to decrease, thus causing a decrease in the potential of the grid 18 causing an increase of the plate current, thus energizing the relay 27 and short circuiting the resistance 6. This causes an increase in the alternator voltage to compensate for the normal drop of volts due to increasing load. Fig. 2 shows an alternative method, dispensing with the relays. The anode of valve 15 is connected to transformer reactance 40. As the valve plate current is increased the inductance in the field circuit decreases and permits an increase of current to flow across the D.C. exciter 46, thus increasing the alternator voltage.

Title: Improvements in or relating to the synchronous control of independently driven machines
IPC: G03B31/00
Filed: 1929-04-30
Abstract: 332,924. Hedinger, F. H. April 30, 1929. Gramophones associated with kinematographs. - Synchronous control of motors driving a cinematograph projector and a gramophone is achieved by the governing motor T, Fig. 4, rotating a brush 30 over distributor segments 27, and the governed motor P, which tends to run slightly faster, rotating a brush 12 over segments 9. When synchronism is destroyed, relay S opens and inserts resistance in series with motor P to slow it down. At starting, motor T may be run slowly with a diverter resistance r, which is removed by a relay controlled by the two distributors as soon as phase coincidence is obtained, at which time relay S also closes and motor P starts. One of the distributors is shown in Fig. 1. The shaft 3 drives a gear train 15, 16, 17, and rotates the brush 12 over the segments 9 fixed to the stationary casing 5. The other part 4 of the casing, carrying the gear 16, is rotatable so as to adjust the phase relation between the distributors. The other distributor has its gears so arranged as to allow the interchange and thus the obtainment of different speed ratios of the. two motors.
